I think stability is directly related to how much stamina is drained when you block a hit. I'm sure someone with more knowledge than me can give you some math behind it.Not sure how in depth it's covered... but the shield section in this wiki might have more info.

Each attack you block will consume stamina, higher stability equals less stamina lost. For some heavy attacks (especially at low levels) the difference between 63 and 76 could be the deciding factor to leave you standing on your feet after a block.The stamina cunsumption ability of weapons will also be increased by upgrading them.

Interestingly if you 2 hand Havel's shield and block you take no stamina drain. At all. Your regen will pause when you get hit but there is no loss.

I'm pretty sure its a percent, as in 63 stability, your shield will absorb 63% of the attack, and the other 37% (which isn't the same value if you got hit), your stamina takes. I'm not sure, but I think its a solid way to think about it.

The highest stability is a Crystal Tower Shield (I'm pretty sure, I never make those stupid crystal weapons) at 90. If you two hand it I bet you gain stamina back when you block

I dont think it is a percent. Think about an attack that does 500 dmg. You block with a 100% shield with 52 stab. You dont take nearly 250 stamina drain. I think its based on weapon percentage (the stamina drained) and then the percentage is applied to that. So GS might deal 100 while UGS does 150.
